In your very last sentence there; you summed up what I meant. I don't know why you expect me to come up with a solution on how to manage societies in a comment section.
Maybe some nice corp would be willing to buy an issue of a journal so that you can publish and distribute the solution!
I have a medium article in draft over 3 months on this exact topic. That's why my wording of the issue came out sounding more complicated. But other commenter saying "science alone" and me saying "using science solely" are basically pointing to same understanding.
There are many examples in history for the said situation leading to social catastrophes; see Malthus (or Thanos' ideology if you like pop-cult), or Darwinian take on managing societies. Some lead to racism, some eugenics etc etc.
Like the original commenter said; science is myopic and highly focused on the present body of knowledge available. But once we applied those results onto people and cause suffering, and 10 years later find some of those were wrong, we can not undo the human suffering.
There needs to be a balance; when science is treading closely to the human dignity, well-being, life in general.
